Navien Tankless Water Heater Repair in Haverhill
Navien units are known for their advanced condensing technology but can sometimes experience issues with their circulation pump or exhaust systems. BWM Plumbing provides dedicated Navien tankless water heater repair in Haverhill, addressing common problems like ignition failures or condensate drain blockages. Our team is familiar with Navien's parts and troubleshooting protocols, ensuring a precise and effective repair that maintains your unit's high efficiency.

Condensing Tankless Repair in Haverhill, MA
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.
Electric Tankless Water Heater Repair in Haverhill, MA
Electric tankless units offer a compact solution but can encounter problems with heating elements or circuit breakers. BWM Plumbing offers expert electric tankless water heater repair in Haverhill, MA, addressing electrical faults, ensuring proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Tankless Descaling and Flushing in Haverhill
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.
Noritz Tankless Water Heater Repair in Haverhill, MA
Noritz tankless heaters are known for their sturdy design, but can sometimes face issues such as flow sensor faults or venting problems. We provide dedicated repair services for Noritz units in Haverhill, MA, ensuring proper combustion, water flow and exhaust, which are essential for safe and efficient operation.
Flow Sensor and Thermistor Repair in Haverhill
Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are accurate.
Tankless Repair vs Replacement Cost in Haverhill, MA
Descaling service typically costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

Ignition Failure Repair in Haverhill, MA
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.

Frequently Asked Questions About Tankless Water Heater Repair in Haverhill
The cost of tankless water heater repair in Haverhill varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after diagnosing the specific problem.
Yes, our technicians are trained and experienced in repairing all major tankless water heater brands, including Rinnai, Navien, Noritz, Rheem, Bosch, A.O. Smith and more. We carry a wide range of common parts for various models.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require special tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a licensed plumber.
Common signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.
We repair Navien, Rinnai, Noritz, Rheem, Takagi, A.O. Smith, Bosch, Stiebel Eltron and EcoSmart units, among others.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still wise.
Regular maintenance, particularly annual descaling, is important for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues early.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
